Can anyone tell me where I can get a copy of a Di-glot? I'm not looking for
the normal greek-english NT's, but one that I think was published by the
Jehovah's Witness. It has been a long time since I saw one and need someone
to point me in the right direction.

I have an older Emphatic Diaglott (1942 edition). It is a word for word Interlinear in the first 2/3's column of the page with an English translation in the rightmost 1/3 column. His preface puts much emphasis on departing from what he considers to be the archaic language of the Authorized and Common versions.

Here is what the Title Page says:

The Emphatic Diaglott
Containing the
Original Greek Text
of What is Commonly Styled the
New Testament

Interlinear Word for Word English Translation
A New Emphatic Version
Based on the Interlineary Translation, or the Renderings of Eminent
Critics, and on the Various Readings of
The Vatican Manuscript
